STEAM-HE'ATING' APPARATUS.

SPECIFICATION forming part bf Letters Patent No. 781,467, dated. January31, 1905. Application filed July 26,1904. Serial No. 218,201.

To all whom, it may concern.

Be it known that I, VVILFRED SHURTLEFF, a

citizen of the United States, residing at Moline, in the county of RockIsland and State and operation of partsare as hereinafter described,reference being had to the accompanying drawings, in which 1 f Figure 1is a sectional elevation-of a portion of a building in which my improvedapparatu's is shown arranged. Fig. 2 is an enlarged view, part beingbroken away, illustrating the details of construction and arrangement ofthe regulator. Fig. 3 is an enlarged section of a pipe connected withthe condensing-radiator and provided with a check-valve. Figs. 4: and 5are horizontal and vertical sections illustrating the construction ofthe heatradiators and their arrangement relative to the wall of a room.

Referring in the first instance especially to Fig. 1, A indicates aboiler, which maybe of any preferred construction, the same beingconnected with the chimney D by pipe at and provided with a water-gagea. B and B indicate heat radiators located in different rooms orapartments of a building and connected by a pipe F with the steam-spaceof the boiler A. Each. of the radiators is provided with a valveoperated by hand-lever 6 for the purpose of regulating admission ofsteam, as may be required by the conditions of the respectiveapartments. The radiators are connected by a return-pipe G with thewater-feed pipe E, which is attached to the lower portion of the boilerA. A condensingradiator O is located in another apartment of thebuilding, and it is connected with the livesteam pipe F by means of apipe F. The ra diator has a small pipe 0, which connects with the saidpipe F and serves to remove water of condensation.

It is further provided with an air-escape pipe -H, leading to thechimney D, and in saidpipe is arranged a check-valve it, as shown inFigs. 1 and 3. This valve is constructed in a well known manner andhinged so that it opens to slight pressure. It seats backward, as shown,so that air is prevented fromaccess to the pipe H from chimney D.

\ The apparatus, which in view ofits function I term the regulator, isillustrated in Fig. 1, but more plainly in Fig. 2. A sphericalwater-holding vessel I is supported at the end of the longer arm of ahorizontal lever J,

the same being fulcrumed at f in a hanger K with a rigid or fixed'pipeM, which in turn connects with the feed-pipe E, as shown in Fig. 1. Theupper side of the Water-holder I is in the same way connected by aflexible pipe N with the steam-pipe F. The latter is also provided witha valve 0, the same having a lever P, which is weighted at one end andjointed at the opposite end to a sleeve Q, that slides upon a verticalrod R, which is pivoted at r to the lever J and also at its lower end tothe arm 8 of the damper S, arranged in the boiler escape-pipe a. It isapparent that the aforesaid rod R will rise and fall vertically,corresponding to the vertical oscillation of the water-holder I and itslever J The valve 0 is normally closed, and the sleeve Q has a certaindegree of free sliding movement on the rod R, it being arranged betweena head r and collar 1".

From the foregoing description the operation of the regulator inconnection with the other parts of the entire apparatus will now beunderstood.

It will be understood that the water-holder I'is ordinarilycounterbalanced by weight L, so as to allow one pound pressure in theboiler A. Steam generated in the boiler A passes by pipe F to theheat-radiators B B, its admission to the latter being regulated by cocksor hand-valves b, as required. The radiators are of such size thatpractically all the steam is condensed in cold weather, so that whenthere is one pound pressure in the boiler there is no pressure inradiators B B or the return-pipe G, the water of condensation returningin pipes G E to the boiler A by gravity. In case of the productionot'fsurplus steam or steam beyond a certain predetermined amount onepound pressureit is drawn oli into the condensingradiator (J, when itscondensation produces a vacuum. The normal water-level in the boiler Ais indicated by dotted line :10, Fig. 1, and the horizontal median line9 indicates the height to which water is raised by one pound pressure ofsteam in the boiler above the normal atmospheric pressure, and it isobvious the radiator G will be entirely empty until such pressure isreached. In other words, such pressure causes water to rise in feed-pipeE, whence it flows through pipes M M into holder I. The weight of waterthus accumulated in holder I causes the latter to descend a shortdistance, which movement carries down the fulcrum of the rod R, so thatthe boiler-damper S is nearly closed, the steam-valve 0 remaining fixedin position by reason of the sleeve Q of valve-leverPsliding on the saidrod R. If now the heat in the fire-box causes generation of steam beyondone pound, it is obvious the water column will rise still higher inpipes E and G, and consequently in the holder or vessel I also, and thelatter being thus weighted to a further degree it descends farther thanbefore, and consequently closes or nearly closes the damper S, so thatthe draft in the fire-box and the generation of steam are lessened,while the steam-valve O is opened at the same time by reason of thecontact of the head 1 of the descending rod R with the sleeve Q of thevalve-lever P. This of course allows surplus steam to escape into theradiator C, where it is condensed and serves as a means for heating theroom in which said radiator is located. The water of condensationreturns to the boiler by pipes c, F, E, and. E. The air accumulated inthe heat-radiators B B and return-pipe G is drawn oli at the same timeand passes from radiator G through pipe H to the chimney D, a returncurrent being prevented by check-valve h. The boiler, pipe F, andradiators B B having been thus relieved of surplus steam and the firedampened, the normal status is restored, the water flowing back fromholder I through pipes M M into the feed-pipe E and boiler A.

It is apparent the operation above described will be repeatedintermittently so often as the steam-pressure exceeds the pressure forwhich the regulator is set.

The preferred construction of the heat-radiators B and B is shown inFigs. 4 and 5, and the latter illustrates the arrangement of the same inrecesses in the adjacent wall X. In other words, the radiators areplaced near the floor along the Wall, and thus occupy the place of theordinary base-board, whereby space is economized and a decorativeell'eet obtained.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent. is-

1. The combination, with a steam-generator, a heat-radiator and a pipeconnecting the two, of a condensing-radiator and an interposed regulatorcomprising a movable watm holder connectedwith the boiler, a valve inthe steampipe extending to said condenser, and a damper in theboiler-flue, both said valve and damper being operatively connected withsaid water-holder, substantially as described.

2. The combination, with a steam-gelaerater, heat-radiators and aconnecting-pipe, of a condensing-radiator and a means for regulating theescape of surplus steam to such condensing-radiator, the same comprisinga movable water-holder connected with the water-space of the boiler, avalve in the pipe connecting the steam-space ol the boiler with thecondensing-radiator, and means operatively connecting such valve withthe said water-lmlder, whereby the vertical movement of the latter,

dependent upon the amount of water forced into it by steam-pressure,operates the said valve automatically, substantially as described.
